LoadVesuvio needs to support summing separate ranges into spectra in same workspace

[Martyn Gigg]

LoadVesuvio currently has a SumSpectra option, which collapses all of the data into a single spectrum.

The instrument scientists would like the ability to specify multiple ranges that are then summed separately into individual spectra on the output workspace, i.e. LoadVesuvio with

Spectra="135-142,143-150", SumSpectra=True

would produce an output workspace with 2 spectra: the first the sum of spectra 135-142 and the second the sum of spectra 143-150.

Branch: In ​mantid and ​systemtests

Tester: The following script demonstrates the idea of the changes. The data is in the systemtests repository.

runs = "14188"

# Examples of spectra strings that are now expceted
spectra = "135" # Load single spectra
spectra = "135-148 # Load range and if SumSpectra is true, collapse to single spectrum
spectra = "135-148;152-165" # Load ranges and if SumSpectra is true, collapse to 2 spectra: the first sum of 135-148 and the second sum of 152-165

sum_spectra = True
diff_opt = "SingleDifference"

data_nosum = LoadVesuvio(Filename=runs,
                         SpectrumList=spectra,
                         Mode=diff_opt,
                         SumSpectra=True)
